Boost Sales with OpenCart Back in Stock Notifications

The Product Stock Notification Alert extension replaces the default "Add to Cart" button with a "Notify Me" button for out-of-stock products. When customers click on this button, a subscription form pops up, allowing them to subscribe to receive notifications when the product is back in stock.

Customers will be notified via email and optionally SMS when the product stock is updated by the admin. This feature helps store owners track product demand and enhance customer engagement by keeping them informed about product availability.

If you require both "Add to Cart" and "Notify Me" functionalities for out-of-stock products, our team can provide a customization service. Contact our support for more details.

Problem Statement

Many customers leave a website when they see an out-of-stock product, resulting in lost sales and missed revenue opportunities. Store owners also struggle to track which products customers are waiting for. Without a system to notify customers about restocks, potential buyers might never return to make a purchase.

This extension solves this issue by allowing customers to subscribe for stock alerts and automatically notifying them when the product is available again, ensuring they return to complete their purchase.

Purpose of the Extension:

The Product Stock Notification Alert extension helps store owners retain customers by keeping them informed about restocks. It enhances user engagement, provides valuable insights into product demand, and improves overall customer satisfaction.

Ivan Arnaudov	07/12/2019
This is the second time I buy a module from HuntBee and the first time I needed help from the author (Priyo) to adapt the operation to my OpenCart theme (Fastor over OC 2102). His response was quick and courteous, he spent a substantial amount of time to make the necessary changes exactly as I wanted them to be. This is why I am happy to give 5 stars both for plugin functionality and for product support. I am very happy with my newest purchase! Ivan Arnaudov - Webstage

janderson	12/08/2015
This extension is awesome. I was having some trouble getting it to work but the dev fixed it quickly. He did a little custom work on the notify and add to cart buttons too. He also a really nice guy and was very pleasant. I would recommend this to anyone who needs an extension with this functionality. You wont be disappointed.

Bob	12/08/2015
This extension is really nice. I didn't fully understand the scope of what this extension was capable of but it was a pleasant surprise to see all the options that are available in the Admin panel. Also, I was having some trouble with getting the extension to work(no fault of the extension but rather my theme) and the dev fixed it quickly and even did a little custom work for my notify buttons. Super nice guy too. I would recommend this extension to anyone looking for something like this. Great support and awesome extension. Thanks again!
